    Notes: Abstract During the past three decades, Nishimura's reciprocal translocation lines of rice have been used in rice cytogenetics to locate genes on chromosomes, to number extra chromosomes of trisomic series and to associate individual linkage groups with specific chromosomes. In this report, we present our identification of the chromosomes involved in 11 of Nishimura's translocation lines using both meiotic pachytene and mitotic prometaphase chromosome analysis. In addition, the numbering of the 12 linkage groups suggested by Nagao and Takahashi, and modified later by many workers, has been revised to agree with the numbering of the identified chromosomes.

    Hyphal anastomosis inPyricularia oryzae cav. (1977)
    Springer

    Notes: Summary Hyphal anastomosis inPyricularia oryzae occurs naturally in the lower epidermal cells and in the vascular bundles of young lesions on rice. In those cells the invading blast fungus are active. Two hyphal cells lying side by side start an anastomosis by forming two, one from each, very short penetration pegs which are opposite to each other. The cell wall of the pegs and the wall in the vicinity of them are then gradually eliminated and thus form a fusion aperture of 0.2–0.6 μm in diameter that is big enough for the migration or exchange of nucleus and cytoplasm between two hyphal cells. The explanation of genetical variation inP. oryzae may be sought on the basis of the ultrastructural evidence of hyphal anastomoses presented in this paper.
